From the back side of the display frame, route the cable from the display over the top bar, then through the hole on the bottom bar, and finally through the passthrough on the camera back cover. Do not install any of the cable retention brackets/grommets/covers at this point.

Use care when manipulating the new cable. The end with the circuitry and connector on it is extremely fragile. It does not take much of a bend to make a new cable inoperable.
